Abstract
The invention relates to a method for measuring and/or testing a geometric design parameter, particularly waviness, of a planar textile (10), comprising the steps: disposing the planar textile (10) in an intermediate space (26) between a support (20) and a flexible film (22), applying a differential pressure (Δp) between the intermediate space (26) and the environment, so that the film (22) adapts to the planar textile (10), and capturing a surface profile (32) of the film (22).
Claims13
A method for measuring and/or testing a geometric design parameter of a two-dimensional textile, comprising the steps of:
- (a) arranging the two-dimensional textile in an intermediate space between a support and a flexible film,
- (b) applying a differential pressure between the intermediate space and an environment, so that the flexible film adapts to the two-dimensional textile, and
- (c) recording a surface profile of the flexible film.
A method for producing a fiber composite component, comprising the steps of:
- (a) arranging a two-dimensional textile in an intermediate space between a support and a flexible film,
- (b) applying a differential pressure between the intermediate space and an environment, so that the flexible film adapts to the two-dimensional textile,
- (c) recording a surface profile of the flexible film,
- (d) calculating a characteristic value, which describes a layer waviness, from the surface profile,
- (e) comparing the characteristic value with a setpoint value interval, and
- (f) incorporating the two-dimensional textile into a fiber composite component only if the characteristic value lies within a predetermined setpoint value interval.
A device for measuring and/or testing waviness of a two-dimensional textile, comprising
- (i) a support for arranging the two-dimensional textile,
- (ii) a film applicator device for applying a film,
- (iii) a differential pressure application device for applying a differential pressure, so that the film adapts to the two-dimensional textile, and
- (iv) a surface profile recording device for recording a surface profile of the film.
